other threads that are wound around same (as for example when threads of horse hair either accompanied by other threads or alone are required to be encircled by additional threads) in order to bind or enclose the horse hair so as to prevent same from leaving the encircling threads of which they form the core. In the production of the said compounded threads it is essential that the core hairs and threads, or those which are sur- 35 rounded and enclosed by the binding threads or yarns, should follow a path coincident with the axis of the circular path in which the encircling or binding threads travel when being wound around said cores. Heretofore 1 in all cases the compounded threads after being produced as stated have in each case continued in or to follow the said axial path until reaching a position entirely beyond the whole mass of encircling thread and the devices which carry and rotate said thread.

3 member.

According to my invention I mount the mass of encircling thread within a revolving member so that the axis of the said mass of thread is coincident with the axis of the revolving From the mass of thread thus mounted I withdraw the thread through a thread guide situated within the revolving member so that said thread is carried through same for a short space in a path ly- H ing in the axis of rotation. After passing through this central thread guide, I take said thread out of said axial path until it approaches the outer end of the revolving member carrying the mass of thread, and I then conduct said thread by appropriate guides, back to the core threads which enters the revolving member at this part. 'Here the encircling thread encounters and is wound around the core thread so that then this compound thread can be conducted to the outside of the revolving member for a space and forward through appropriate guiding means in order to be conduct-ed back to'the axial path beyond the mass of threads from which it is takento be wound upon a bobbin or to form a cop or to be otherwise dealt with as hereinafter described.

By the employment of the devices and following the method above referred to, I am enabled to form the compound thread by using single hairs or several hairs to form the core of said compound thread. Or I may use another continuous thread in addition to the hairs to produce said core.

In order that my said invention may be readily understood I have hereunto appended sheets of drawings illustrative thereof to which by figures and letters reference is made in the following description Fig. 1 is an end elevation of a pair of rollers arranged to supply the selected hairs and yarns or thread which is fed to them to my improved twisting and wrapping devices shown beneath same.

In carrying my invention into effect I make use of devices such as are described in the specification of my invention set forth in my concurrent application for Letters Patent in the United States dated the 22nd day of April, 1929, Serial No..357,025 which will select a single or several hairs from a bundle of hairs and will supply same so that it or the may be carried forward by appropriate delivery rollers 2 and 3. These rollers are arranged to be rotated. at a suitable speed in unison with that at which the supplying of the hairs thereto may require as is well known in, connection with other types of machine made use of in the production of threads or yarns. I In connection with the devices for selecting the hairs as, above described I make use thread 6 maybe wound around'same. The

encircling movements of the said thread I) are brought about by the cop b which supplies same being placed within a tube 4 which is of the character of a flyer and is formed to receive a spindle 5 carrying said cop Z2 This spindle 5 is inserted within said tube 4 and held in place by its hub 5 resting upon a central cross-pin 4 fixed in the lower end of the tube 6;

The supply of thread Z) fromthe cop b is taken endwise and vertically through the uide 470 which is in alignment with the axis of the spindle 5, so that said thread may pass through an opening a formed eccentrically through the end walls 4?) of the tube 4 (see Fig. 9). The opening 0 is made through a short tube as shown by Fig. 9 so that said thread I) may pass through said tube and (in order to effect a slight drag thereon) be wound half the way, or a little more than this, around the lower end of the funnel shaped member 40 which is fixed upon the upper end 4?) of the tube 4. From this position the thread b is then taken through a radial opening 0 formed near the base of the cup shaped member 40 in order that it may then encircle the thread a as the tube 4 is rotated and as the cop b is also rotated by and with said tube 4.

The threads and hairs (1 together with the wrapping or encircling thread 12 (forming the compound thread a are then taken downwardly through the central opening in the upper end wall 41) of the tube 4 and from this position said compounded threads are carried to the outside of the tube 4 (Figs. 1 and 9) and made to pass down the outer surface of said tube 4 and forward to be delivered as is hereinafter explained.

The tube 4 has the lower part of its outer surface provided with ribs 4d (which are shown to be four in number by Fig. 3 but which may be three or more than four'in number) which extend upwardly along same so that they will fit snugly within an outer rotary sleeve 6 while a notch made crosswise I in the end of the tube 4 will span a cross pin 4a fixed upon the sleeve 6 in order that said tube 4 with its cop b may be rotated by and when the external tube 6 is rotated.

The lower end 6a of the tube 6 is made of smaller diameter and has mounted upon it a wharle or driving pulley 7 around which takes the driving band deriving its motion from. any appropriate source (as in an ordinary spinning machine) well understood, and

which will transmit rotary motion to said wharle 7'in order that by said wharle 7 being secured by a nut 7a upon the extension 6a of the tube 6 said tube 6 may be rotated as desired.

To facilitate the rotary motions ofthe tube 6 and the parts which revolve with it I have inner ball races 7 and g mounted respectively upon its lower and upper extremities while outer ball races h. and k are received within bearings 8 which are pivotedat 8a upon a suitable bracket 9 that is fixed upon framework 9a'as isshown by Figs. 13 and 14.

' Fixed upon the hinged bearings 8 are lever arms 10 and 10a see Figs. 13 and 14. The arm 10a reaches vertically so that by engaging with an actuating spring p which is fixed upon the retaining catch 11, the attendant may arrest the motions ofthe parts as is'hereinafter explained. v

The retaining catch 11 is pivoted at 11a upon an extension from the bearing 8 in order that a handle 12, which forms the extension of the'holding catch 11, may occupy a convenient position for the attendant to handle and operate said holding catch 11. The lever 10 extends horizontally to enable a rod 103) to be connected to the hair supplying devices which conduct same to the rollers 2 and 3, for the purpose hereinafter explained. Also from said lever 10, a connecting rod 13 is -made to reach into connection with a lever 14 pivoted at 144i upon abracket supported by the framework of the machine 15.

This lever 14 has an extending arm llb upon which the gripping roller 2 is mounted so that when said lever 14?) is held in its pos'ition shown by Fig. 13- a spring 16 will cause the lever 14: and its arm 14?) to press the roller 2 against the roller 3 and therefore grip the threads and hairs passing between it and said roller 3. V

In accordance with one arrangement of the devices in connection with the lever 10 above described I make use of another connecting rod 17 which is pivoted upon the lever 10 and reaches down to enable a supporting pin17a fixed to it to take beneat the arm 18av of a'lever 18whichis pivoted upon a shaft or stud 19. Upon the arm 18 of the said lever is mounted a gripping roller 20 which is arranged to press against another roller 21 which roller 21 (in a similar manner to the roller'3 hereinbefore described) ,is caused to revolve at the desired surface speed to carry forward the thread a which is delivered through the lower end 60 of the tube 6 as shown by Fig. 11.

WVhen the lever 10 is raised, as is herein after explained, to lift the lever arm 18a it causes the arm 18 to remove the gripping roller 20, from engagement with the roller 21. lVhereas when the lever 10 is in its operating position as shown by F ig. 13 then the spring 22'will force the roller 20 against the roller 21 to grip the threads passing between them as desired. i

When the rollers 20 and 21 are made use of I may arrange same to deliver the compounded and encircled thread a down to a bobbin 23 as is shown by Fig. 11. This bobbin 23 rests upon the peripheries of two rotary drums 24 and 24a. so that as these revolve in the di- .rection indicated by the arrows to they will cause the bobbin 23 to revolve to coil upon it the yarn a as said bobbin-23 revolves under well known-conditions.

The guiding of the thread backward and forward over the surface of the bobbin 23 in order to effect the building of same, is carried out by a reciprocating bifurcated thread guide 25 which is operated by well known means used in ordinary thread winding machines.

hen the apparatus is in operation with .the handle 12 adjusted in its position shown by Fig. 13, the hook 11 is in engagement with a projection 95 formed on the rail of the framework 9a and by being thus in connection with the said projection the holding catch 11 retains the bracket 8 and all the parts it carries in their respective positions shown by Fig. 13, an d in these positions the effective operations of the several parts are carried out. The rollers 2 and 3 are moved to deliver at the desired rate of speed (according to the change wheel gearing by which the roller 3 is rotated) the yarn to enable the compound thread a to descend through the parts 4?) down on the outside of the tube a forward down through the lower end of the tube 60 to be fed to the rollers 20 and 21 as before stated.

Provided one or other of the threads breaks or fails to be in continuity or provided the supply of hairs gives out or fails, then the attendant may by pushing the handle 12 into tie position shown by Fig. 14 to disengage with hook 11, cause all the parts to be brought into their respective positions shown by Fig. 141.

vv hen the parts assume these positions the rollers ant. 3 are separated (by the roller 2 being moved) the driving band which transmits motion to the wharleor pulley 7 is allowed to become slack and said pulley 7 is forced by the actions of gravity on the pivoted members 8 and the parts it carries, into engagement with a brake 26 which is fixed upon a bracket 26o carried by the framework of the machine.

hen the motions of the pulley 7 are thus bring same back into its ordinary position shown by Fig. 13.

lVhen it desired to wind and form the compound thread 642 on to a bobbin or spool ready for use in the shuttle of a loom I make use of another tubular member 2? as shown by Fig. 1. This tubular member forms a shield or cover for a central spindle 28 upon which a bobbin 29 is mounted. This spindle 28 held against rotation and the bobbin stakin loosely over same rests upon a disc 28a carrying a drag washer while the usual and well known vertically reciprocatory transversing motions are transmitted to the spindle 28 and its bobbin 29, to carry out the building of the coils of threads upon said bobbin 29 as usual in machines for carrying out spinning and like operations;

Upon this sleeve 27 2 re mounted the driving wharle 30 which by the two pairs of antifriction bearings 30a and 30?) the wharle 30 is supported, and this wharle 30 carries ext asions 31 which form a fiyer by which. the compounded thread a is brought downward throu connections 00, 00 upon the leg of the flyer 31 so that the rotations of said fiyer may wind the said threads upon the bobb n 29 which is carried by the spindle 28.

In Figs. 1, 8, 9, 10 and 11 a cup shaped extension is mounted at the upperend of the tube but instead of said cup shaped member I may make useoi? a disc 4h which has mounted upon it the thread guide 470 through which the thread I) carried and this thread 7) is carried through the-said guide 41*: to pass through the opening 0 and around the small groove 4m beneath the disc 4th so that it may pass through an opening m and therefore beneath a spring 32 as shown by Fig. 5. This spring 32 acts as a guide for the compounded threads, instead of the tunnel shaped member lo.

When making use of the flyer 31 for winding the threads as above described, and ar ranging same as shown by Fig. 1, I find that on account of the false twisting or twist tube actions on the threads at which are delivered bythe rollers 2 and 3 during the rotations of the flyer 31, said twisting commences imme diately the threads leave the rollers 2 and 3 and onpassing downwards through the opening b at the upper end 46 of the tube t and just prior to emerging from said uppcrend the thread 6 from the cop b is wound around the said'false twist or core threads and by running the flyer 31 at about half speed of; that of the tube 4 and in th same direction, the core threads a are encircled by the threads 6 from the cop b in the opposite direction to the false twist of said core threads a so that a complete encircling of the core threads secured and this is desirable when the core threads which are twisted together as stated are of cotton and the encircling thread I) from the cop b is of silk or of artificial silk or like more costly material. I
